13 - Module.exports and Require()
In Node.js, the module.exports object is used to define what a module will make available for use in other modules. It is a special object provided by the CommonJS module system in Node.js.
Using module.exports allows you to structure your code in a modular way, making it easy to reuse and organize functionality across different parts of your application. Keep in mind that this pattern is specific to the CommonJS module system used in Node.js. If you're working in a browser environment that supports ECMAScript modules, you may use export and import statements instead.
